Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention "Field of Industrial Application" The present invention relates to balls such as baseballs, and in particular, on the 19th pitch, the ball leaves the pitcher's hand and enters the catcher's hand. To provide a ball capable of automatically measuring time or speed during fishing.

``Conventional technology J'' Conventionally, when measuring pitching speed, the configuration was such that infrared rays were applied to a moving object such as a ball at a location far from the pitching position, and the reflected waves were used to measure the velocity. .

``Problems to be Solved by the Invention'' However, according to the conventional structure described above, the device is lrlm, and handling is troublesome, and measurement is performed by indirect means using infrared radiation. However, it has disadvantages such as the inability to perform accurate measurements.

"Means for Solving the Problems" In order to solve the above problems, the present invention provides a measuring function inside the ball, and includes an electronic arithmetic circuit element, a display device connected thereto, a power supply, and a switch. Equipped with elements, and these! In addition to being covered with an IWIJ material, at least the portion facing the display surface of the display device is provided with a cover made of a transparent material.

[Function J] In the above configuration, the electronic arithmetic circuit element, the display device connected thereto, the power supply and the switch element are covered with a ball-shaped t1 impact material to protect them from external impact during pitching. be able to. Furthermore, by providing a cover made of a transparent material on the front surface of the display device, it can be viewed from the outside.

The above-mentioned electronic arithmetic circuit element includes a manually operated reset switch and an I/O circuit as switching elements connected to the electronic arithmetic circuit element.
By providing a stop switch activated by I, the ball can function as a counter from pitching to catching.

“Example” The present invention will be explained with reference to an example shown in the figure below.
is an electronic arithmetic circuit element including an integrated circuit, etc., and the electronic arithmetic circuit element 1 includes a display device such as a liquid crystal! 2, a battery 3 for power supply, a reset switch 4 configured to be activated by manual operation, and a stop switch 5 configured to be activated by impact;
The stop switch 5 is composed of a ring-shaped contact 51 and a weight-shaped contact 52 formed at the end of a spring swingably mounted in the center of the ring-shaped contact 51. It is integrally protruded. Also, inside the casing 6 is a buffer made of synthetic rubber or the like.

The electronic arithmetic circuit element 1, display device 2, battery 3, etc. are housed through a protective member 61 made of a suitable material and having an appropriate thickness. On the other hand, an integral cover 7 is formed from a cushioning material such as synthetic rubber in the form of a hollow spherical body of an appropriate thickness divided into two parts, and a recess 71 formed on the side of the integral cover 7 is provided with the above-mentioned reset button. The switch 3 is installed, and the flange 62 of the casing 6 is fitted into the stepped recess formed at the joining part of the two halves to hold it, and the casing 6 is positioned in the space within the cover unit 7. . Further, the cover unit 8, which is paired with the cover unit 7 and faces the window portion of the display surface of the display device W12, is formed of transparent synthetic resin. Furthermore, an exterior body 9 of an appropriate thickness made of an elastic material such as soft synthetic resin is integrally formed around the outside of these integrated covers 7.8.

With the above configuration, when the reset switch 4 is pressed, the contents of the counter of the electronic arithmetic circuit element 1 are reset, and this state is maintained as long as the switch 4 is pressed. Next, when this ball is thrown to a catcher who is at a predetermined distance, the counter of the electronic arithmetic circuit element 1 moves from the moment the hand leaves the reset switch 4, and the contents are displayed on the display device 2. . Next, when this ball lands in the catcher's grip, the contact 52 of the stop switch 5 contacts the contact 51 due to the impact, and the counter operation of the electronic arithmetic circuit element 1 is stopped, and the contents at that time are displayed on the display. 2 and can be visually observed through the cover unit 8.

``Effects of the Invention'' As described above, the time it takes for the ball to leave the pitcher's hand and enter the listener's hand at the pitcher's riA (electronically; If the distance from the pitcher to the pitcher is determined in advance, the speed of the pitch can be detected relatively from the above measurement time.

In particular, by positioning the casing of the electronic circuit element in the space within the cover integrally formed into a ball shape from the above-mentioned cushioning material, it is possible to protect the electronic device such as the above-mentioned electronic circuit element from impact when catching a ball. Furthermore, the results can be directly viewed through the transparent cover as the contents of a display device connected to the electronic arithmetic circuit element.
